An Oxford graduate is concerned he can no longer visit the San Francisco office of his London startup

Eamon Jubbawy, the cofounder of London startup Onfido, is
concerned he can no longer visit his company's San Francisco
office because he is of Iraqi origin.

President Donald Trump signed an executive order last week that
that has temporarily halted visa holders from seven
majority-Muslim countries from travelling to the US. The
countries affected are Iran, Iraq, Libya, Somalia, Sudan, Syria,
and Yemen.

Jubbawy, a British citizen who studied economics and management
at Oxford, is currently in London and he does not think he'll be
able to travel to the US any time soon.

"My parents were born in Iraq and, although I had planned to
travel next month, the ban is pretty unclear with regards to what
is and isn't allowed," said Jubbawy.

Despite what the US Embassy in London said, No. 10 claims that British citizens with dual
nationality will not be affected by Trump's travel ban if they
are travelling from the UK.

Onfido has raised $30.3 million (£21.5 million) for its software
that helps businesses like The Daily Mail and sharing economy
startups like BlaBlaCar to verify that employees and contractors
are who they say they are

Jubbawy started the company with fellow Oxford graduates Husayn
Kassai and Ruhul Amin in 2012. The business —headquartered out of
an office above London's Covent Garden Tube station — has grown
to employ around 100 people, with 10 of those based in San
Francisco.

"Until the executive order, we didn't really care about who's
from where or what religion they were, we didn't ask, but all
these things have been a distraction and worrying," Kassai told CNBC.

Kassai, who was born in Manchester, moved to San Francisco
recently to grow Onfido's business in the US.

Kassai, who also studied economics and management at Oxford
University, is a dual citizen with an Iranian passport and a UK
passport. He also holds a US green card which means he's not
directly affected by the immigration ban.

But that doesn't mean he'll stay there.

"I need to decide by this week if I'm going to leave the country.
I just need to check with the lawyers if I'll be able to come
back," Kassai told CNBC.
